FAQ

What is the maximum DDR-1 data rate supported by KMPC8560PX833LC?

KMPC8560PX833LC supports DDR-1 SDRAM at a maximum data rate of 333 MHz, delivering 5.3 GB/s peak bandwidth over its 64-bit interface. This is validated for 1 Gbit x8/x16 DRAM configurations with full ECC enabled and page mode support up to 16 open pages. The controller complies with JEDEC DDR-1 specifications and requires 2.5 V SSTL2-compatible I/O signaling with MVREF = GVDD/2.

Does KMPC8560PX833LC support RapidIO packet ordering across priority levels?

Yes, KMPC8560PX833LC supports reordering across priority levels in its RapidIO interface unit. It implements four priority levels with ordering within each level and explicit reordering capability between levels - essential for maintaining strict latency bounds in distributed baseband processing. Packet payloads are limited to 256 bytes, and CRC protection is applied end-to-end per packet.

What power sequencing requirements apply to KMPC8560PX833LC?

KMPC8560PX833LC requires strict power sequencing: VDD and AVDD must be applied first, followed by GVDD, LVDD, and OVDD. Voltage rails on the same line have no relative order, but rails on subsequent lines must reach 90% of target before the next group reaches 10%. Violation risks latch-up or undefined boot behavior. The recommended core voltage is 1.2 V ± 60 mV for the 833 MHz speed grade.

Can KMPC8560PX833LC operate in PCI agent mode?

Yes, KMPC8560PX833LC's PCI/PCI-X controller supports both host and agent modes. In agent mode, it functions as a peripheral device responding to configuration and memory-mapped I/O accesses from an external PCI host. This enables use in modular chassis where KMPC8560PX833LC serves as a line card processor interfacing with a central switch fabric via PCI-X.

How many independent TDM interfaces does KMPC8560PX833LC support via its time-slot assigner?

KMPC8560PX833LC supports eight independent time-division multiplexed (TDM) interfaces through its time-slot assigner. These interfaces handle T1/CEPT, T3/E3, PCM highway, ISDN PRI, Freescale IDL, and GCI formats. The assigner multiplexes data from up to four SCCs and three FCCs onto these TDM links, enabling consolidated voice/data transport in legacy telecom systems.
